CAR-TRUCKS.

class wherein the journal boxes are rigidly secured in the truckside-frames, and wherein the truck bolster is supported by springs in orupon said side-frames. In a truck of this class the truck-bolster isusually of about the same length as the car axles, and its ends extendthrough or beyond the side frames, the bolster springs being arranged inthe vertical 'planes of the sideframes. 7 7 1 I The object ofmyinvention is to improve the con struction of the side-frames of cartrucks of the class mentioned, and the particular object of theinvention is to providean improued cast-steelside-framefor cartrucks. I

Further and particular objects of the invention are to providesingle-member cast-steel side-frames of such character that'the bolstermay be inserted into the openings .of said frames after the frames and.journal boxes have been placed upon the truck wheels; further, toprovide an improved single-member side-frame which shall becharacterized asabove and which nevertheless, shall have continuous oruninterrupted top and-bottom chordal portions or flanges. Otherobjects-of my invention will appear hereinafter.

My invention consists generally in a railway car tiuck andparticularlyin the improved side-frame for such truck, all as!hereinafter described, and particua larly pointed out-in the claims.

The invention will be more readilyunderstood by reference to theaccompanying drawings, forming a part of this specification, in whichFigure lis a sideelevation or" a railway car truck embo'dying myinvention; Fig. '2 is'a; partial plan view thereof; Fig. 3 is an?enlarged side view of the-middle portion of my nov'eli'gg'g frame; Fig.4 is a vertical sectionthereoi, on theiiflfiDLJV oi Fig.3; Fig. 5 is ahorizontal'section onlin V QV: of Fig. 3; Fig,' 6 is a view like untoFig,, 5, illustrating a bolster guide or v column block of modifiedform; and Figs. 7, 8 and 9 are like views, disclosing guidebloclis ofstill other form;

As shown in the drawings, 2"2 represent the wheels oi a car truck; 33,-,the axles, and 44 the journal boxes. 5 represents the truckbol'ster,-and 55' the? bolster gtudea forming a part of the bolster. Theparts of the trick here naehtio ied may be of.an-y suitable dle of thebeam; is of greater 'width than the bolster form and constructionadapted for employment with rigid side-frames, My novel side framecomprises a single steel casting, A, having ends, B, that are adapted torest upon the,

tops of the journal boxes, and at the middle provided ,with an openiug,C, which latter is at all points or heights of greater width than thebolster, 5, including its guides, 5. I,prefer that the side-frame shallpartake of the form of an irregular but symmetrical flanged beam, and ashere shown it comprises a web portipn, D, and top and bottom flanges orchordal portions, E and F; the middle of the beam is ofconsiderabledepth, as required to accommodate the bolster and thebolster springs, while theends are of much reduced height. The ends ofthe beans are secured upon the journal boxes by the usual box orpedestal bolts. It willbe understood that the dip or drop of the middleportionof the beam maybe as little oras great as-requ'ired, to

adapt the trucks to cars of various heights. A tie bar or bars, 6, ofsuitable form, may be employed to tie or brace the journal boxes at thebottom, or the beam, A, may itself be formed'to brace said boxes.

As stated, the rectangular opening/O, in the midand its guides. Mypurpose inthus constructing the side frame is to facilitate theassembling and the disas thebolster may be inserted or threaded endwisethrough the side-frame, it is unnecessary. to delay the assembling ofthe truck until the bolster has been -Ineniberment 0f the truck, and itwill be obvious that placed, or to first remove the, side frames fromthe journal boxes, preparatory to the removal of the bolster. It isnot-even necessary to remove the bolster springs, v7, from theside-frames. In other words, certain means which I employ for guidingthev bolster in the side-frames are of such character that the fullopening of the side-frame above the springs is at all times availablefor the insertion or removal- 0f the bO l': ster; hence, the bolster maybe readily placed in or removed from the truck after or while the sideframes are rigidly secured together and-.iupon the journal boxesythebolster guiding means rejferred tol'comp'rise short blocks,'GG' which al'removably secured in 'theupper part of the side-frame opening. Thesefit the bolster guides and constitute jtheiac tual""'guidei" columns oftlie sideframes although as hereinafter de scribed the side frame hasits own integral column-r portions. As shown in Figs. 3, 4 and 5, Iprefer to provide the frame or. beam, A, with side flanges orprojecting-ribs or columnportions, H-H framing the upper part of theopening, 0. These flangesor coh vumn portions do not extend-to thebottoni of the beam; instead, notches or recesses, Hfl are providedtherein at the lower part of the opening to adinit the guide blocks, G.E:a;clrguide-lolock comprises 'a's mall,

angular casting, shaped to fit the cross-sectionaliorm of the columnportions, H, of the side-frame. (See Figs. 4 and 5.) When the bolsterand the springs have been placed in' approximate position within thesideframe, the blocks G, are inserted at the lower part of I the openingand are then raised or slid upwardly into interlocked position with theflanges or column portions, H,'in which position they enter .the guides,5, of the bolster. 1 Little labor is involved in thus securing thebolster by means of the guide blocks or separablecolumns. Eachguide-block, G, is secured to the web onthe sidefranie Joy-two bolts,.G, and each block carries a brake-hangerbracket, G formed'integrallytherewith. Thus in one operation the bolster is secured .inplaceand the.side-frame is prepared toreceive the brake-beam hangers. p I

A non-essential and yet desirable feature of my sideframe resides in the.widenedlower flange, F, of the beam which adds to the strength of thebeam andprovidesa perfect spring-seat.

A substantial equivalent of the column block, G, above described, may behad, and the employment ofthe flanges, H,'may be avoided by forming theguide or column block in the manner shown in Fig. (SJ This block,l, hasan inner portion, 1, of sufficient width. to fit the bolster-guide 5 andits outer portion is bifurcated to fit the web portion D of theside-frame to,

, which it is secured by a bolt, 1 Here, .as before, the;

brake hanger bracket is an integral part'of the guideblock. 8illustrates a form of my side-frame in which the guide-block J and thehanger, bracket J are separate parts, the latter, J, being integralwiththe side-frame. In 7 I have shown my invention ina form adapted foremployment with bolsters having guides 5 which are not in alinement withth side-frame. In this case the guide-block, K, and the hanger-bracket,K, are applied: to one side only of the side-frame, being secured bysuitable bolts, K

Fig.7 illustrates another form of the guide-block applied to the innerside of the beam or side-frame, but occupying a central position. Inthis case the web portion D of the frame is provided with a guide-blockpocket or recess, L in its inner side adjacent to the large bolsteropening. The block, M, fits the pocket and is secured'bya bolt, M. Here,as before, the l prising a sideframe made of a singlepicce of metal,provided with a bolster andspring opening and'having short device lendsitself'to ready combination with the brake-hanger bracket, M
